WINDOW AN REGULATOR GOUPLING.-

Application filed August 23, 1922. .Seria1No.583,22.

To* all whom t may concern:

Be it known that Ennns'r E. citizen of the United States, residing at Detroit, in the county oflliayne andSta-te of Michigan, has invented certain new and useful niprovement-s in 4lfVindow and Regulator Couplings, of which the following is a specification. l

This invention relates towindow regui) lators. It has for its object, a window regulator'which has a quickly detachable connection with the sash. `This connection is of such a character that the windowmay be removed from the window well without4 rel moving the trimming material or any ofthe boards around, the window well.

Figzl is aside elevation of door 'showing the trimming material removed, and equipped with my improvement.

Fig. 2 is a sectional view on the line 2-2 `of Fig. 1.

Fig. 3 is aiperspective'of the iixture attached to the cable. v

Fig. 4 is an enlarged elevational view showing" the detachable connections between the sash and cable.

Fig.` 5 is a similarview showing the detachable connection just after the same has been broken. i

Fig. 6 is a section taken on line 6-6 of Figa.

Fig. 7 is a perspective of the latch lever' used in the detachable connection.

Fig. 8 is a perspective in detail showing how the sash plate is connected to the bottom of the sash.

The various parts ofthe window regulator will be apparent fromthe drawing without giving any detailed description. The regulator here shown is described and claimed more particularly in my- United States Patent No. 1,486,963. It happens to be one that employs a cable a which winds around an elongated drum b, rotated by a crank handle c through connections which `need not here be detailed. Any -form of regulator of this general type may be used. It matters not whether vit is a chain driven regulator or a cable driven regulator.

It is customary in regulators of this general type to employ a flexible lift member. This is usually provided with a pin which engages in a slotted plate on the bottom of the sash. This construction works very HEINTZ,

nicely but in case itis `necessary t0 detach the windowfrom the regulator, the trimming material `and often some of thcboards in the body have to be remeved. lt is the object of the present invention to wholly elimii'iate this trouble. yInstead of an ordinary pin secured tor thedra-ft member, I employ vfixture d, which is simply .a stampedclip that. can be soldered or otherwise fastened to the cable. In its general configuration, the clip is dcvetailedtongue, that, is, when viewed `in plan.

`Gnthe bottom of the `window sash is securedthe usual plate e. `This plate however, has a diifcrent form ofislot, than is ordinarily the case. The slot extends vertically upward from the bottom. and has an enlarged opening, f, `with beveled sides. On oneside of the slot, the metalis turned up 'i to form thestop/t. Above the slot is piveted the latchlle'verfa The lower end of this `lever is provided with a'tu'rned over ear, e', which is guided on Vthe .segmentally shapedpin j, secured to the .luga struck out of the plate e, a coiled spring m normallytends to press thelatchleveragainst the stop 7L, causing they hook orbillend` of ,the latch lever toclose the-opening of the .slot f and prevent: the escape ofthe fixture CZ when thatis, inthe slotg Thelheadofthef85 latch lever is beveled as at 0, and projects only part way over the entrance of the slot 7,

as plainly shown in Fig. 4.

It will be obvious that the fixture el is` fairly rigidly held on the draft member or cable. Hence when the window is detached from the regulator, and it is desired to again couple it to the regulator, all one has to do is to insert the window in the window well and cause the window plate to be guided down against the fixture d. The central or narrow portion of the fixture can be caused to enter the slotf. This will ordinarily displace the latch lever because of the bevel o on its head. When the fixture has passed into the main portion of the slot, the latch lever' will snap behind it and ordinarily couple the two members together.

In order to release the plate from the fixture the latch lever is provided with a projecting arm g, which extends through the segmental slot 1" as clearly shown in Fig. 2. Some form of a tool, like a screwdriver, bar, or the like, may be inserted down into the Vwindow well between the window sash and the wall of the window well. This tool may be swung to open the latch g, and permit the window to be disengaged from the cable.

that I claim is:

l. In a window regulator, the combination of a window sash, a lifting member, and a detachable coupling between the two, including a slotted plate secured to the sash, a spring-pressed latch for guarding the opening in the plate, and a fixture secured to the lifting member which may ordinarily displace the latch in entering the slot in the plate, but which requires manipulation of the latch to release i 2. In a window regulator, the combination of a window sash, a lifting member, and a detachable coupling for the two, including a slotted plate provided with an enlarged entrance slot, a bevel-headed spring-pressed latch guarding the entrance of said slot, and a fixture on the lifting member that may ordinarily displace the latch by engaging the beveled head and enter the slot, but which requires manipulation of the latch to release the members.

3. In a window regulator, the combination of a window sash, a lift-ing member, and a detachable coupling for the two, including a slotted plate provided with a stop, and having an enlarged opening leading into the slot, a bevel-headed lever guarding the opening of the slot, and having a projecting arm which may be reached by a tool vfrom the top of the window well, a spring which normally presses the latch lever against the stop, and a fixture on the lifting member that ordinarily displaces the latch by engaging against the bevel head thereof and enters the slot, but which requires the latch to be displaced by a tool inserted in the top of the window well in order to release the coupling.

t. In a window regulator the combination of a window sash, a lifting member and detachable coupling between the two comprising a device that can automatically lock when the sash is engaged with the lifting member but which requires the use of a tool when the sash is disengaged from the lifting member.

5. In a window regulator the combination of a window sash, a lifting member and a detachable coupling between the two including an automatic latch member which permits the engagement of the two and which 'can be disengaged by the use of a tool to retract the latch.

6. In a window regulator, the combination of a window sash, means for lifting the window and holding the same in any intermediate position of tra-vel so as to govern the opening of the window, said means including a vertically traveling lifting member, and an automatic coupling between the window sash and the lifting member which causes the sash to be automatically coupled up with the lifting member when the sash is pressed down on the lifting member.

7. In a window lifting device, a window supporting member, a means for raising and lowering the supporting member, an elastic clip secured to the window frame and having an engaging nose for elastically engaging the supporting member whereby the window may be readily connected and disconected to and from the supporting member.

In testimony whereof I afhx my signature.
